Abstract
BACKGROUND
Meningioma in the cerebellopontine angle (CPA) without dural attachment is extremely rare. We report a unique case of meningioma derived from the superior petrosal vein without dural attachment.
CASE SUMMARY
A 44-year-old right-handed woman presented with a two-month history of headache and tinnitus. Brain magnetic resonance imaging showed a well-defined contrast-enhancing lesion in the right CPA without a dural tail sign. Tumor resection was performed using a right retro sigmoid approach. A dural attachment was not seen at the tentorium or posterior surface of the petrous pyramid. The tumor was firmly adherent to the superior petrosal vein. The origin site was cauterized and resected with the preservation of the superior petrosal vein. A diagnosis of meningothelial meningioma was made. The patient’s headache and tinnitus gradually disappeared, and a recurrence was not observed five years after the surgery.
CONCLUSION
The rare occurrence of meningioma without dural attachment makes it difficult to determine dural attachment before surgery. The absence of dural attachment makes it easy to completely resect such tumors. Vessels related to tumors should be removed carefully, considering the possible presence of tumor stem cells in the microvessels.
Core Tip: The rare incidence of meningioma without dural attachment poses challenges in preoperative determination of dural attachment. However, the absence of dural attachment facilitates complete tumor resection. Careful removal of vessels associated with tumor is important to remove tumor stem cells in the micrvessels.
